` ORNAMENTI.- CHAIN-LINK.

SPECIFICATION forming part of Letters Patent No. 253,351, dated Februaryf7, 1882.

' Applicationniea December 7,1881, (No'modei.) l

To all whom it may concern: v

Beit known that I, SALOMON DAVIDSON, a

-citizen of the United States, residing at New York, in the county andState of New York,

have invented new and useful Improvementsin Ornamental Chain-Links, ofwhich the following/,is a specification.

Thisinvention consists in a chain-link comprising a tubular bod-y withrecesses formed in said body at its ends and collars embracing' the tubeand fitted in said recesses; and it further consists in the tubular bodyrecessed and having an ornamental plateftted upon `said body and engagedby said collars, asV

hereinafter more fully described.

f This invention is illustrated in the accompanying drawings, in whichFigure l represents a sectional side view ot'fa chain constructedaccording to my invention. Fig. 2 is an end View ofa chain-link. Fig. 3is a trans# verse section of the same in the plane xx, Fig. 1. Fig. 4 isa transverse section in the plane y y, Fig. 5 is a sectional side viewot a chain-link with ornamental plate. Fig. 6 is an' end view of thesame. Fig. 7 is a sectional and side view of a modication ofthe same.

Similar lettersindicate corresponding parts. In the drawings, the letterA designates a tube, which may be square or polygonah'as shown in Figs.2 `and 3, or round, as shown in Fig. 4. This tube is out to the requiredlength fora chain-link, and it is provided with one or morev recesses,a, which ,if the tube is square vor polygonal, arefformed in the edgesthereof; or when the tube is round the recess or recesses extend cleararound, or partly around, their depth vbeing such that they do not eX-tend through the thicknessof the metal from which the tube is formed.These recesses serve to receive the collars b, which, when compressedinto the same, are firmly retained in position lwithou-t solder andvWithout swagin g. The connecting `devices B, as shownin the drawings,consist l of links c', .which vextend through the tubes A, and in theends of which are secured rings d,. but any other suitable cornectingdevice may be used with'my chainlin By securingthe collars b in therecesses a much timeand labor are. saved, since by dispensing with,solder notonly the time for soldering is saved but the labor requiredfor bnrnishing the links is materially facilitated.

In practice I use for each link two collars, which are secured inrecesses near the ends of ,the tubes used in the construction of thelink.

4I fthe tubes are square or polygonal, as shown Yin Figs. 5 and 6, thecollars also serve to retain ferent ways; or, ii' desired, my link canbe used Without such Ornamental plates; or the body of the tube may beornamented with perforations or other devices. Furthermore, each linkmaybe provided with one, two, or more collars, according to taste.

In order to enable me to apply the ornamental plates-0 to round or ovaltubes, Imake the same in the form of a shell, which is iitted on thetube, as 4Shown in Fig. 7, so that the l vwith the link, or attachedthereto in a suitable manner, and suitable'ornaments may be used, asdescribed, with reference to the tube.

Whatl claim as new, and desire to secure by Letters Patent, is-

1. In achain-liuk, the tube having recessesf a at its ends, with one ormore collars embracingthe tube and fitting in said recesses,substantiallyas described.

2. The combination, in a chain-link, of the tube A, having at its endsthe collars b, fittedl into recesses inthe tube, and an ornamental platearranged upon the exterior of the tube andengagin g at its ends with thesaid collars, substantially as described. In `testimony whereof -I havehereunto-set my hand yand seal in the presence of two subscribingwitnesses. v SALOMON DAVIDSON. [L. S] Witnesses:
